{{Quote|Our peers at Aperture Science were at work on a project of some promise, but in their rush to beat Black Mesa for funding, they must have compromised ordinary standards of risk.

The '''''Borealis''''' is an Aperture Science research vessel introduced in ''Half-Life 2 Episode Two''. According to Isaac Kleiner, Aperture was working on a promising project, but in their rush to beat Black Mesa for funding, they neglected ordinary safety rules and the ship simply disappeared with parts of its drydock, which earned it a legendary stature. It is assumed that the ''Borealis'' contained an immensely powerful and dangerous secret, most likely involving portals and teleportation on a larger scale than that of a '''handheld''' portal device, which is likely the reason the Combine are searching for it as they could possibly connect back to Combine Overworld and flood the planet with their large and powerful armies. The Combine also have yet to perfect localized teleportation, as the Black Mesa scientists and Aperture Science have, giving them ample reason to investigate the ship.

===''Half-Life 2 Episode One''===

Many years after the Combine invasion of Earth, Judith Mossman, Resistance operative, finds the ''Borealis'' in an Arctic location. She is attacked by Combine forces soon after, and is only able to send an incomplete transmission of her discovery to White Forest. This is intercepted by the Combine, and in turn stolen back by Gordon Freeman and Alyx Vance from the Citadel Core during their flight from City 17.  

===''Half-Life 2 Episode Two''===

After safely reaching White Forest, Alyx and Gordon deliver the data to the Resistance, which reveals that Mossman was cunning enough to encrypt ''Borealis'' photographs, coordinates, blueprints and hailing frequencies within her message. Once Eli Vance and Isaac Kleiner have decoded these and realize the full significance of the transmission, a rift opens between the two Resistance leaders. Kleiner believes the technology the ''Borealis'' contains could be used by the Resistance against the Combine to aid them in The Uprising; Eli, haunted by memories of the Black Mesa Incident and not wanting a second Seven Hour War, believes that the ''Borealis'' has to be destroyed at all costs.

It is not clear whether the Combine know of the ''Borealis'', and consequently if they themselves have some interest in the ship's contents. Given the attack upon Mossman's forces, the interception of her message and the death of Eli Vance, it seems very likely.

While the nature of the secret hidden within the ''Borealis'' is unknown, one of the blueprints indicates the presence of at least a Aperture Science Material Emancipation Grill|Material Emancipation Grill and an Aperture Science Unstationary Scaffold|Unstationary Scaffold within the ship.

Mossman's message goes as follows

{{Quotation|''I'm fairly sure I've pinned down the location of the Project. It's hard to say how much of it might have survived intact, or whether there's anything remaining that could compromise our work... if it were discovered by the Combine. We'll need to take a close look at it, of course, but I should be able to give a better opinion within a few hours. If the site is where we think it is, then it should be no more than... I'm going to cut this short. We may have been spotted.''}}

===''Portal 2''===
FileBorealis drydock.jpg|thumb|right|200px|The ''Borealis''' empty drydock.

In ''Portal 2'', the ''Borealis''' drydock can be found in the 1970s section of Test Shaft 09, near the offices where Chell finds GLaDOS in the bird's nest. The drydock is obviously empty, save for several life preservers bearing the ship's name scattered on the floor. FilePortal 2 Borealis Lifering.jpg|thumb|Borealis life Preserver

This is a nearly unbelievable location in which to place a large ship; the elevation of the drydock is approximately 3975 meters below the surface, as noted on the wall in the nearby inaccessible lobby of the main shaft elevator on this level. There is no other mention of the ship's presence in, or disappearance from this area. Considering the ship's mysterious disappearance from shaft 09 and subsequent reappearance in the arctic suggests an accident involving the quantum tunneling research being performed by Aperture.

Next to the entrance of the dry dock there is an intercom you can click on that mentions that they are working on a Teleportation experiment, leading the player to believe that the ship was teleported. This appears to agree with the fact that perfecting localized teleportation was something the Combine and the Resistance were working on in ''Half-Life 2'' and its episodes.

===''Half-Life 2Episode 3 / Half-Life 3''===

FileBorealis Advisors.jpg|thumb|left|100px|Concept art for ''Episode Three''

The ''Borealis'' is expected to appear in ''Episode Three''. The first revealed concept art features a ship, with the word "B--EALIS" on it, the O and R being covered by Combine technology. It is stuck in ice, and Advisors float through the canyon, suggesting that the Combine will have already discovered the ship when and if Gordon reaches it.

==Behind the scenes==

*The icebreaker ''Borealis'' was originally to appear in ''Half-Life 2'', Borealis (cut location)|as the ''Hyperborea'', then the ''Borealis''. In Marc Laidlaw's first pass at the game's script, Freeman was to start the game by boarding the ship, bound for City 17.http// The Final Hours of Half-Life 2, Page 6 The Hemoglobin, on GameSpot Later in the game's development, it was to appear between two other cut chapters, the Air Exchange and Kraken Base,''Half-Life 2 Raising the Bar''WC mappack before being eventually cut with the whole part set between the Depot and the City 17 street battles.

*The name "Borealis" is likely associated with the term "WikipediaAurora (astronomy)|aurora borealis", the northern polar lights only visible in the Northern Hemisphere. "Borealis" comes from "WikipediaAnemoi|Boreas", a wind god in the Greek mythology. "Hyperborea", the early name for the ship, was the name of the land of the WikipediaHyperborea|Hyperboreans, a mythical people who lived far to the north of Thrace. "Hyperborea" means "beyond the Boreas", thus beyond the land of the wind god Boreas. "Aurora Borealis" is also the name of a European research icebreaker being constructed.http// Official website of the ''Aurora Borealis''

*The images hidden in Mossman's message are located in the ''Episode Two'' texture files, in the folders "effects" and "Props".

*Other images include three blueprints of the ''Borealis''. The original images are not blueprints for any of the United States Coast Guard research icebreakers mentioned above but those of a naval warship, the WikipediaUSS Newport News (CA-148)|USS Newport News, a United States Navy heavy cruiser launched after World War II. They also feature tables, taken from other blueprints. The images also feature a QSL card, originally for the USCGC ''Polar Star''.

*The ''Borealis'' seen on the screen at White Forest can be found within the map "ep2_outland_11b" and accessed with the "noclip" console code.

FileNO BOAT.jpg|thumb|right|"Ship Overboard" Achievement icon.

*One Portal 2 Achievements and Trophies|''Portal 2'' Achievement/Trophy named "Ship Overboard", with the description "Discover the missing experiment", requires Chell to find the ''Borealis''' drydock.

*The ''Borealis''’ teleportation mishap shares many similarities to the urban legend of the WikipediaPhiladelphia Experiment|Philadelphia Experiment in which the warship WikipediaUSS Eldridge (DE-173)|USS ''Eldridge'' was rumored to have been rendered invisible by experimental technology. In some versions of the story, the ship had accidentally teleported from its dry dock to a U.S. naval base over 200 miles away. In the most radical versions of the story, the ship achieved accidental time travel.
*While the ''Borealis'' was apparently located in an area of the Enrichment Center built in the 1970s, the ship's blueprints feature GLaDOS' name where the corporation's owner would sign, as well as the modern Aperture Laboratories logo. This issue has yet to be addressed or retconned.
*As stated in an email from GLaDOS to GLaDOS, the ''Borealis'' was designed to be very durable, while everyone thought that it was a simple icebreaker ship. It also had very little in the way of supplies for a crew, and was stripped of anything not necessary for so that there was a lot of space for it.http// Email from GLaDOS to GLaDOS
